Toall whom'it may concern:

Be it known that I, Armor Mom'nm, a citizen of Switzerland residing atOberwintert'hur, Switzerland, ave invented certain new and usefulimprovements in Coke-Cooling Apparadis, oi'whichthe following is aspecification.-

It is already known to utilize the high temperatures of hot coke leavingthe retorts, for the generation of water gas, by quenching the coke byintroducing steam'in an airtightly closed chamber and passing the watergas formed to further utilization. The steam required for this purposeis uiually tapped -from an existing steam boiler p ant.

This process has the drawback, that only the heat of an upper zone oftemperature of the incandescent coke can be employed since with atemperature of the coke below 600 degrees centigrade ageneration ofwater gas will, no longer take 700 degrees centigrade it will-becomeuneconomieal t9 such an extent, that it can not be carried throughpractically,- The heat oi the lower zone of temperature, that is to saybelow 7 00 C. is thus lost. Besides it is necessary to generate the'steam required. for the generation ofwater gas by a correspondingconsumption of fuel, which procedure will. minimize the profit obtainedby the formation of water gas.

In the new process according to the invention both the water gas and thesteam required for that purpose are obtained by means of the heatcontained in the incandescent coke. ing the heat yielded at an upperzone of temperature from a quantity of coke contained in a receptaclefor making water gas, while the heat gained at a lower zone oftemperature irom the same charge of coke is used for the: generation ofthe steam required for the formation of water gas, the whole procedurewith the object in view to dispense with a specialsource of heat for thegenera tion of steam.

The installation for carrying out this process. may be of suchconstruction that the stoking hole or fireplace of the boiler servingfor thegeneration of steam, is connected with the receptacle containingthe coke by means of pipes capable of being shut, and through which,after opening of the shutting-oil members, the gasescontained in boththe communicating chambers, for the pur- The process consists in utilizpose of conneying the heat of the coke into the boiler, are forced bymeans of a blower m "a cycle through the rece tacle and the boiler. Theplant may also e of such construction, that condult through which thewater gas generated may be conducted either directly or through thestoking hole of the boiler to the place of consumption.

A mode of drawing.

a is a receptacle into which the coke coming from the retorts isintroduced throu h the opening I) and after the finishingof-t e coolingprocess is discharged through the outlet 0. 0! represents a boiler,whose stoking hole is connected at the top with the receptacle a bymeans of the pi e e and at the bottom by the pipe f A bower 'v is arranged in the duct fforcing the gases contained in the receptacle forthe coke and the etching hole in a cycle through both chambers, in orderto transfer the heat, withdrawn from the coke by the gas, to the boiler.g and h are shutting-oil" members provided for the purpose oftemporarily interru ting the communication between the coke 0 amher andthe stoking hole.

construction is shown in the Connected with. the steam chamber oftheboiler is a steam pipe c" leadin to the coke chamber, by means pfwhich t e steam required for thegeneration of Water gas is conducted tothe coke. For regulating the admission of steam said pipe is providedwith a controlling member is. The water gas generated is passed throu hthe pipe Z provided with a closing mem r m to an accumulator or as thecase may be to the place of consumption.

Another pipe at having a closing member 0 serves for conducting the hotwater I gas through the etching hole or fire place of the boiler withthe ob ect of utilizing the heat of the gas. v

The plant is operated in such a manner, that the total amount of heatyielded b' the first filling of the container 0; is use for thegeneration of steam. For this purpose the closing members 76, m and oare shut, and e and f opened, and the blower o started, whereby the usesforced through the communicating c numbers in cycle, transfer the heatof the coke to the boiler water,'and cause va o'rization of the latter.

If so cient steamis generated in this way, the container a is dischargedand filled pipes are provided again wiehincandescent coke, the closingdescent coke by openingihe controlling 5 member is. The water gasgenerated hereby is conducted through the conduit pipe to theaccumulator or piece of consumption re emetweiy. As soon as the cokecooling down has reached a temperature of about W 70%, the members m and7c are closed, but

g and h opened, and by starting the blower '21 izlie beatsiaill inherentin the coke is again utilized for." the generation of steam. In

this manner is possible to generate the i 4 f s efi sheen: leqnireo 101*one oimation or water gas foiiowing next.

After the complete coolin of the coke the container is clischangeci 2m anew charge of incandescent coke brought in, when after a correspondingadjustment of she olosing members he formmbion of watei gas and thesubsequent generation of steam commences anew. Instead of leadi the hotwater gas, leaving the coke container, to the accumulator directly or tothe place of consumption, said gas can. also be conducted through oponin-the member 0,, where its heat is utilize in an economical way for thefurther aeration of steam.

Io aim: o A plant for dry cooling coke comprising in combination acooling chamber, a steam boiler connected therewith, a valved means forintroducing steam from the boiler into the chamber, a valved means fordrawing oif water-gas and valved means for circuthe boiler by closingthemember m and.

latin a cooling gas through the chamber.-

and t en through the boiler.
